Alright, I'm a complete newbie with Unity, and I thought you guys might be able to help. At the moment, I'm making something along the lines of a small test game, where the player is able to control a ball or marble. I added a rigidbody to the ball, and when i started to script it, I ran into a dead-end. At first I used rigidbody.AddForce() but it seemed unrealistic. I tried to get it to move by using rigidbody.AddTorque(), but the ball doesnt seem to roll fast enough. I tried multiplying mainly, but no matter how high i put the numbers, the speed remained the same. I cant find any other ways to do this. Is there something im missing?

rotation speed is limited by a setting in physics settings. just go to edit/project settings/physics and change the value of max angular velocity. don't set it to a really high value because it can produce errors. i use this code for rolling and it works well i defined maxspeed, ratio and speed as variables in top of my code. i don't copy whole code because it's C# code and you don't use it. it has many other stuff too. the ratio variable is the ratio between z axis and x axis movements. the movement is natural even with max angular velocity of 7 (default). don't change the value if you don't have to do so. it can result in a ball that pass other colliders.

If you are using the Iphone version of Unity you can check out the Unity demo Roll-A-Ball: http://unity3d.com/support/resources/example-projects/iphone-examples It's a simple roll-the-marble-past-the-holes type of game. Even if you aren't using Iphone you may be able to pry some useful tidbits out of it. :) --Goody!
